Charged for new card while the existing card is not lost.

Good day. Nedbank has always given me good service. Last week I went to deposit money at the ATM Tzaneen. I forgot my pin and the card was swallowed. When the bank opened later the morning I went in. The staff of Nedbank opened the ATM and found my card. Because my name is not written on the card they said they need to issue a new card. Today I see I have been charged R145. Why, my card could have been just activated again? I was also not told I will be charged. I did not loose my card. The staff had it in front of me.
